Rockets streamed out of Gaza and Israel pounded the territory with airstrikes early Wednesday as the most severe outbreak of violence since the 2014 war took on many hallmarks of that devastating 50-day conflict, with no endgame in sight.

Let us take a look at what is Israel's Iron Dome Defense system:
